Lost Link is an application that analyses HTML files and checks links are live. i.e. The files referenced are available. It provides a report of good and dead links for a single HTML file or an entire web site. The application will benefit web page authors who wish to easily verify that their pages have valid links. The HTML file may be stored locally or on the Internet. The web is a dynamic place with referenced sites and pages constantly changing or being deleted. This application will enable a rapid assessment that the links are still valid.
